What is Ten Percent Fines Value Test (TFV) | Test Procedures
Aggregates used in construction should be strong enough to resist crushing under loading conditions. If the aggregates are weak, the integrity of the structure may be adversely affected. The strength of the aggregates here is measured in a crushing test. The TFV gives a relative measure of an aggregate to crushing under a gradually applied load.
